There is a HashMap contains 7 Keys, which is Monday through Sunday. Each key is corresponding to a List of (Start time, end time) pairs. The pairs is unsorted. What I have to do is to merge the time slots that are adjacent. And finally return another HashMap that contains the same structure but with merged time slots.
